The song was originally written by Delacey (Halsey's "Without Me
") and Michael Pollock. It was birthed when a tearful Delacey found herself crying on the shoulder of her sister after exiting a toxic relationship. The songwriter recalled to Billboard
that she said to her, "Isn't it crazy how someone can just totally ruin your life?"
Delacey added that "'Ruin my life" is something she "says all the time because I'm a drama queen." Thinking it could be used in a song, she wrote the phrase in her notes.
Later, during a session with songwriter Michael Pollack, she mentioned "ruin my life" as a potential title and he loved the idea. "It felt like there could be a good juxtaposition with the lyrics," Delacey said. "It's such a negative title, but it's this beautiful love song about someone you want to stay in your life because they make it better… even if it feels like a bombshell."
